The NTP client is disabled by default.
If NTP is configured on a system whose current time differs from the NTP
server time by more than 10 minutes, convergence of the WX time can
take many NTP update intervals. 3Com recommends that you set the
time manually to the NTP server time before enabling NTP to avoid a
significant delay in convergence.
